Underwater 2D is a browser-based 2D adventure set in the eerie depths of an alien ocean. Your mission is simple but dangerous: collect the required fish to complete the dive. But you can’t stay under forever — your oxygen tank is always ticking down. Find refill zones scattered through the water before your air runs out. Meanwhile, dangerous fish and hazardous seaweed-like plants drift through the same currents, and one wrong touch can end your mission. Gather what you need, survive the unknown, and finish the dive.
